We must protect you at all costs. You’re amazing. Thank you

[@michellec3385]

for the longest time i couldn’t wrap my head around indirect vs direct no matter how many times i went over it but your explanation finally made me understand! thank you 🤩

[@esteph0812]

I remember that Amorphous Silicon is used in Indirect conversion because Silicon and Indirect both have two "i"s. Also, Selenium and Direct both have one "i" :D

Wow I needed this! Thanks so much!

[@dannyvang1990]

This video was very helpful and helped me understand it in detailed! Thank You! 🙌

[@destinyperez5913]

You teach it better than my teacher !!!!

[@emilycharn1036]

That was great to watch. Thanks for the video.

[@mendoza725]

Great review for boards! Ty

[@maririvas9258]

Thank you so much, this was super helpful. You explained it so perfectly! Feeling much better about my understanding on this subject after watching your video 😀

[@meaghanpiretti7340]

You're so welcome!

[@nomadicsuraj]

Very simply presented thank you madam.

[@SGSJR31]

Great video thank you!

[@reshmasaldanha5087]

thank you..

thank you so much omg

[@meaghanpiretti7340]

You are welcome!

[@abdovitamins6331]

Great explanation ❤ but I am kind of confused about fill factor and it's relationship with sampling interval. So does fill factor fall as the pixel sampling interval is reduced of the opposite is true?

[@meaghanpiretti7340]

Fill factor and sampling frequency are two different concepts. You want the DEL to have a high fill factor for higher spatial resolution.

[@nabidolati4825]

Hello, do you have any information, formula, or program about DR digital radiography with X-source and especially gamma ir192 so that I can calculate the radiation time?

[@josebonilla4544]

very nice done. You can repair this array tft?

[@meaghanpiretti7340]

Can I repair it? I am not a clinical engineer so I don't know that answer.

[@231mac]

So.... indirect goes from electrons (from the cathode) to photons (X ray) to photons (light) back to electrons? Okey dokey...

[@meaghanpiretti7340]

I think you might be confusing things in the x-ray tube with the Imaging plate. This video explains how the digital plate converts the x-ray photons that interact with it into the digital image.

[@231mac]

@@meaghanpiretti7340 Not confusing them, as I was combining both from start to finish, lol. But, I do see where my verbiage is off and causing confusion. Great video, btw! I begin rad school in August and I'm attempting to gather knowledge before classes start.
